De la Introducción, escrita por Pablo Hernández Balaguer:
Uno de los aspectos más interesantes de la obra musical de Esteban Salas, son los Villancicos. Estas breves composiciones para voces e instrumentos – cuyo pasado se remonta a la época de los trovadores – lejos de ser obras sin importancia constituyen, quizás, la muestra más elocuente de su talento.
Esteban Salas y Castro (December 25, 1725 – July 14, 1803) was a Cuban composer of religious music. His compositions focused chiefly on vocal music, and are a fine representation of the late Baroque style. Although heavily influenced by French and Italian works of the period, his music is considered to incorporate an original Latin American component. He became a teacher and head of music at the Chapel of Music at the cathedral of Santiago de Cuba from 1764. He also studied theology and canon law and was ordained a priest in Santiago de Cuba in 1790. Salas composed his last carol for Christmas 1801.
